Horrified tourists saw their tour guide stung to death by crazed giant wasps, who then feasted on his body for four days.

Sanchai Phaoarun, 58, was taking a French couple sightseeing in Chiang Mai, northern Thailand last Saturday (October 26) afternoon.

But mid-way through a mountain trek the group was suddenly surrounded by thousands of angry hornets after their hive was disturbed.

They dive-bombed Sanchai and repeatedly stung him across his body. The guide collapsed on the ground in agony while the terrified couple, from France, fled in panic.

Locals from the nearest village heard crying for help from the two tourists, Jean Louis L’amour and Anne Mapile, who had also been stung. They were taken to hospital.

Rescue workers found Sanchai’s dead body later that day but they were unable to retrieve it as it was still being feasted upon by the killer Asian hornets, or vespa velutina.
